Builder / Prototyper / Engineer
Steven Barnett
I prototype next-gen AI tools and harnesses — turning research ideas into working systems that push the boundary of what agents can do.
About
I'm a software engineer focused on agentic AI systems — the intersection of large language models, tool use, memory architectures, and autonomous reasoning. I build prototypes that test the edges of what's possible with current models.
My work sits in the gap between research papers and production systems: taking novel ideas around context engineering, agent memory, and inference-time compute and turning them into things that actually run.
What I Build
Agent Harnesses
Frameworks that orchestrate LLM agents with deterministic control flow — letting AI handle intelligence while code enforces correctness.
Autonomous Scanners
Systems that continuously monitor research and surface genuinely novel insights — not just new articles, but new ideas.
Rapid Prototypes
Quick-turn experiments that validate research concepts — from BM25 deduplication pipelines to multi-stage reasoning chains.
